Title: Disk cartridge
Inventor: HATTORI RYOKICHI
IPC: G11B23/03
Filed: 1986-04-22
Abstract: PURPOSE:To eliminate a need for the accuracy of the positioning of a pin, etc. and to simplify manufacture, assembly, adjusting, etc. by connecting a shutter and a disk clamper to make them act associatively. CONSTITUTION:When a disk cartridge 21 is inserted in the cartridge insertion part of a recording and reproducing device, a pin 41b abuts on a slider 30. When the cartridge 21 is further pushed in, the slider 30 moves in the direction of arrow A, the shutter 28 connected with the slider 30 moves in the direction of arrow B and opens a hole for clamping disk 26 and a hole for recording and reproducing 27. Also, the moving of the slider 30 in the direction of arrow A pulls a shutter spring 38, providing the disk clamper 34 with a clockwise moment around a pivot 35. Because of the moving of the shutter, when the moment due to the shutter spring 38 becomes larger than that due to a disk clamper spring 37, the disk clamper 34 rotates in the direction of arrow C and detaches from a disk 22, and thus the disk 22 is released and made rotatable.

Title: Method for determining three-dimensional coordinates of measuring point using optical range finder/goniometer
Inventor: AOKI AKIO
IPC: G01C15/00

Abstract: PURPOSE:To enhance determining accuracy, by a method wherein a second prism reflecting mirror is arranged at a position separated upwardly from the measuring point on a measuring object by a predetermined distance and a first prism reflecting mirror so as to provide an interval from the second prism reflecting mirror. CONSTITUTION:In order to measure the three-dimensional coordinates of a measuring point, the base 11 of a reflector 5 is fixed to a measuring object 2 so that the measuring point P3 of the measuring object 2 coincides with the central part of the front surface of the base 11 of the reflector 5 and first and second prism reflecting mirrors 6, 9 are turned to the direction of an optical range finder/goniometer. Light is emitted to the first and second reflecting mirrors 6, 9 of the reflector 5 from the optical range finder/goniometer and the reflected lights are received by said optical range finder/goniometer. Then, the three- dimensional coordinates P1 (x1, y1, z1), P2 (x2, y2, z2) of the center positions P1, P2 of the first and second prism reflecting mirrors 6, 9 are calculated and coordinates conversion is performed so that the origin of a coordinates system coincides with P2 and P1 comes onto an X-axis. Because the coordinates of the measuring point P3 come to P3 (-delta, 0, 0), if reverse conversion is performed on the basis of the above-mentioned parameters, the coordinates (x3, y3, z3) of the measuring point P3 in the coordinates system of the original optical range finder/goniometer can be calculated.

Filed: 1988-04-15
Abstract: PURPOSE:To reduce the scale of the title circuit and, at the same time, to improve the responsiveness of the circuit by holding the self-returning of one holding means until the other holding means self-returns. CONSTITUTION:In the section X in which input signals SI1 and SI2 are inputted, with a sufficient time lag being maintained between their rising edges, a holding means 6 is set and its output SO becomes 'H'. While the output SO is 'H', the change in a signal XQ1' passes through a commanding means 2 and resets another holding means 1 as a signal SR1 after the lapse of s delayed time Td1. When the rising edge of the signal SI2 changes, on the other hand, the means 6 is reset and the signal SO becomes 'L'. While the signal SO is 'L', the change in a signal XQ2' passes through a commanding means 5 and a holding means 3 is reset after the lapse of a delayed time Td2. Then, in the section Y in which the signals SI1 and SI2 are inputted, with their rising edges being set closer to each other, the passage of an inhibiting means 4 is inhibited, but enabled after the lapse of the time Td1.
